T0 all (whom. t may concern:

Be it known that l, WILLIAM J; Houses, a citizen of thellnited States, residingr at Atlanta, Vin 'the county of Fulton and State of Georgia, have invented certain new and use- Sound Reprodue'ing Machines,

panyiiig drawings. i

This invention relates to improvementsiin soun'd reproducing machines and hasffor its primary object-to providealdevice of this character wherein the" sound reproducing means including 'the amplifying horn is' `arranged ivithin a single inclosedl chamber whereby the objectionable scratching noise ot the stylus upon the reproducing record is rendered inaudible.

Another and very importantobject of the invention resides in the provision of means for mounting' the' reproducing disk record 'tone arm Whereo-n' the sound box is arranged so as to eliminate the leakage of sound waves and thereby' secure a maximum volume of sou'nd. Another and more specilie 'obiect of the invention is to provide aisiniple and novelA in operative position that material economy may be efect-ed in the manufacture; oli-the disks.

' 'lilith the above and other objects in View as will .become apparent as the description proceeds, the invention consists in certain combinations and arrangements of vthe parts tliatl shall hereinafter full-y describe and claim.

For a full 'understanding of the invention, reference is to be hadto the following description and accompanying drawings, in ivhich Figure 1 is a perspective vieu7` of a sound repro d uci ne; machine emilie-ying the present invention; Fig. Q is -a vertical section thereofg'Fig. 3 is a top plan view, the caselevated therewith.-

vandwitliin the cabinet the horizonta supporting bars 7v are mounted at A.their ends. upon cleats 8 fixed to -the side Wall-s of said cabinet.

cured thereto inany preferred manner the spring motor indicated at 9. This motor may be of any approved construction and *drives a vertical spindle 10 which extends upwardly through a topplate 11 arranged upon 'the supports 7 A shield plate'l en;

'tends from this' top plate 1l to theft-.ont Wall of the casing and protects the partsof the motor against dust yand dirt accumulating thereon.4 Y f In the preferred embodiment o-my in- 'ventiorn the amplifying horn 13 'is-0f rectangular form cross section and its liaring Wider end is fixed tothe inner surface ot the front Wall of the case or cabinet 5.

This' front ivall-ot the cabinet is provided with an elongatedl opening indicated at 111.

which may be of any desired size or o rnamental shape, and said casing' Wall may also have additional sound outlet openings 15 at.

sides of the main openingr 1li.- The top wall ot the. casing is provided with a hinged cover 16 to close the opening 6 theres of, said cove' being supported in its open position by tile usual movable links 17. This cover will be later referred to in detail and opposite These supporting bars l have se-' the purpose .theieofmore specifically pointed out. r The inner end ot the' amplifying horn is disposed adjacentto the rear or back ivall of thee-ase or cabinet and 'is provided with "the usual socket fixed to said Vcabinet wall in which one end of the tone arm 1S is mounted for vertical and lateral movement. The'other end of thistone arm is provided with the usual sound box 19'ivliich is provide ivith'the needle or stylus 20. T o. one of the sidewalls otgthe case or cabinet-, an. in-

wardlyprojecting yieldablle abutmentt''n'ember 21 is secured with which the sound box is adapted to engage to position the tone arm and the needle of the sound'box when it is desired to start the machine so that the cabinet 5, and with thevteeth of the bar a recoil vpivoted latchl plate 25 is adapted to engage, whereby the arm 18 may beheld in an ele rated position. One end of a coil spring 2G is connected tothe arm 1S, the other end of said spring being fixed to the,inner end of the bar 22. This spring yieldably supports the arm in itsplaying position and permits of t-he usual v ibratory inoif'ement. thereof which is due to the oscillation of the rotat-y ing. record disk.

The disk holder designated at 27 consists.

of a circular plate preferably constructed of aluminum and provided at its outer edge with a circumferential flange28, from which flange 'a short arcuate inwardly projecting lateral flange` 29 extends. The bottoin face of this, aluminum plate is covered with felto'r ther suitable fabric upon which the disk gagedga portion of the edge of said record beingfitted between the flange 29 andthe body of the holder. This record disk D is' in the form of an annulus the `central por tion thereof being cut away as indicated at D. Thus a material saving in the manufacture of the disks may be effected, as it has heretofore been necessary to 'manufac ture the same as a substantially solid-.disk having an aperture or small ope ing at its center to receive the perpendic'lar shaft or spindle upon which the disk is mounted.

In a machine embodying thdpi'mpr'onements of the present invention, the body of the holder is provided with a short,` tapering stud 30 projecting from its under surface which is adapted to be fitted in a socket 31 provided in the upper e'nd of the rotary Vspindle 10. vUpon the circumferential flange 28 of the holder plate 27 at a point diametrically opposite the flange 29 'a catch 32 of any suitable form is mounted. 4This catch is adapted to he engaged over the edge of the disk record to `.'etain the same in the holder. Upon. the opposite or upper surface of the holder plate 27 a tubular boss 33 is centrally formed. This boss is adapted to be received in a central' opening 34 provided the hinged cover or top 16, the

upper end of said opening being diametri` -indicated at D is adapted tol be en? gaged by a` facing plate 43.

by means oI suitable screws. Thisv plate is provided with a central threaded opening 38 to register with vthe threaded borcof v. the tubular boss 33. A screw threaded pin` 39 is adapted tobe engaged `with the threads of the plate 3G and of the boss 33, whercl'iy the'disk holder will be connected g to the hinged top 1G ofthe cabinet, The 'upper end of the threaded pin 3l) has pirotally connected thereto a wing or linger piece 40 which, when the machine isnot in use adapted to be turned down into thc annular recess 35 at the upper end of the opening 34 inthe cover. It will be noted that when the disk holder is in position upon the upper end of the spindle 10, the upper surface of said holder is flush with the upper surface of the top of the cabinet. Thus when the cover is movedl downwardly upon the holder, it. will lie perfectly flat. upon the top wall of the cover. The edges'l of this hinged top are preferably provided with strips of felt or other fabric to provide an air-tight closure and also prevent. marring of the surface finish of the cabinet.

41 indicates the starting rod whereby the spi'iiig motor is controlled. This rod projects through an opening in the frontwall of the cabinet. T-lie.motor shaft 42 extends through an opening in the side wall of the cabinet, the -end of said shaft bei'ngflush with the outer surface of said wall and en- This outer end of the 'motor shaft is provided with a. rectangular socket to receive ythe squared end of a winding crank 44. By mounting the motor shaft in the wall the cabinet in this manner, the escape of the sound waves through-the opening in the cabinet wall is obviated and the winding crank may-also be easily and qu'icklyjattached to or detached lfrom said shaft.

From the above description taken inconiiection with the accompanying drawings, it

is thought that the construction and manner of operation of my improved sound reproducing machine will be lf ully understood.

As the to-ne arm and sound box are entirely iiiclosed within thccasing or cabinet..

.substtintially the entire volume of sound will escape from the machine through the amplifying horn 13 -an'd the openings 15 in the. front wall of the cabinet.. ln the usevof the` device, whenit is desired t-o change the record disks, the pin 39 is simply threaded into the boss of the disk holder and said holder together with the hinged top of the cabinet raised.4 The disk may be readily removed `from the holder and another substituted therefor. The cover is now lowered uponthe cabinet and upon removing the pin 3., the disk' tolder will be supported wholly upon the pper end of the spindle 10. The toothed bai-22 is now pulled outwardly through the rear wall of the cabinetso as :ilo
